Central System: Avionics Core - DO-326A Air Shield

Cryptographic Nodes

  • ARINC 664 Sec
  • ADS-B Authn
  • Flight Computer
  • FIPS 140-3 HSM
  • Satcom Telemetry

Architectural Layers & Protocols

  • Airborne Databus Isolation & Security (ARINC 664 Part 7 (AFDX) & MIL-STD-1553 Cryptographic Overlay): Injecting post-quantum authentication into deterministic avionics Ethernet virtual links
  • Next-Gen ADS-B Quantum Authentication (Lightweight Elliptic Curve & Lattice Signature Combiners): Preventing ghost aircraft injection and trajectory spoofing in Air Traffic Management (ATM)
  • Cockpit Voice & Controller-Pilot Datalink (CPDLC) (Post-Quantum Secure Voice and Text Telemetry over SATCOM): Shielding critical air-to-ground air traffic control instructions from eavesdropping and spoofing
  • Airborne Flight Hardware Root of Trust (DO-254 Level A FPGA and Radiation-Tolerant Cryptographic Coprocessors): Isolating flight control cryptographic keys within DO-160G environmentally certified boundaries

Key Metrics: DAL-A (Target DO-178C Safety Level) | DO-326A (Airworthiness Security Framework) | <10 ms (Flight Control Telemetry Latency) | Zero-Spoof (Navigation Integrity Guarantee)

机载平台面临长达30年的量子脆弱性窗口期

Commercial airliners and military aircraft certified today will remain active for decades. Legacy airborne databuses (ARINC 429, MIL-STD-1553, AFDX) were designed without cryptographic authentication, leaving avionics exposed to spoofing and quantum-enabled signal synthesis.
